| 摘 要： | 准确分析混凝土断面的浆体面积对混凝土材料中有效扩散区域的判别和划分具有重要意义。利用计算机图像处理技术研究了混凝土断面上浆体区域和骨料区域判别的方法,并在此基础上准确分析二种不同区域的面积。该方法能够适用于各种混凝土断面形式,避免传统方法需要手工操作、人工度量所带来的低效率、低精度等缺陷。

| Abstract: | The determination of the area of paste on concrete section is very important to the definition of the efficient diffusion field of concrete.A computerized image processing method for the area measure of paste and aggregate on concrete section is proposed.Compared with the traditional methods,the area of paste on concrete section can be discriminated by this method rapidly and accurately,and the presented method is suitable for a variety of cross-section form of concrete. |
